With the E-3 Olympus has developed an impressive array of highly reliable new technologies essential for serious SLR photographers. Olympus cameras have a history of raising the bar when it comes to reliability, toughness and durability - and the E-3 takes it to a whole new level.The E-3 is equipped with a large optical viewfinder that provides 100 percent accurate viewing and 1.15x magnification for reliable composition - what you see is exactly what you'll get. Even fine details are seen with astonishing clarity. The E-3's large, precision-crafted pentaprism is crafted from high refractive index glass with a highly reflective silver coating. The eyepiece uses glass lenses. All the lenses are surface coated to maintain brightness. The focusing screen features a Neo Lumi-Micro Mat for bright, easy-to-adjust manual focusing.Spots on photos are now banished forever. The Olympus dust reduction system is an industry first and a proven technology. Every time you turn on the E-3, our Supersonic Wave Filter - located between the shutter and the image sensor - silently vibrates an amazing 30,000 times per second. Dust is blasted away. The dust reduction system even removes dust attached by intermolecular force that can't be shaken off or discharged with static electricity. Dust will no longer get between you and a great shot.Shoot anywhere, anytime, in any condition. The E-3 body, the built-in flash and the LCD are all splashproof and dustproof. Constructed from a magnesium-alloy with a homogeneous composition, the E-3 is lightweight yet strong and rugged. The same goes for Zuiko Digital lenses. You'll find splashproof and dustproof models that are as tightly sealed as the camera.To ensure you can keep shooting, even at 5 frames per second, Olympus utilizes a durable shutter mechanism tested to 150,000 cycles making the E-3 the perfect choice for photographers who demand the most from their equipment, in any situation.
